3. Zeroing Function
Before taking a measurement, especially in a new environment or after a long period of storage, it is recommended to zero the gauge. With no pressure applied, press the 영 button to reset the reading to zero. This corrects any potential deviation and ensures accurate measurements.
4. Max/Min Value Recording
The gauge automatically records the maximum and minimum pressure values during operation. To view these values, press the 세트 button repeatedly until "MAX" or "MIN" appears on the display. To clear these recorded values and start a new recording cycle, press and hold the 영 동안 버튼 viewing the MAX/MIN display.
